Meanings

noun

The act of putting a liquid, especially a drug or vaccine, into someone's body using a needle and syringe; or the liquid itself.

noun

An amount of money, a resource, or an element that is added to improve a situation, system, or process.

Definition

An injection primarily describes the medical procedure of using a needle and syringe to introduce a liquid, like a drug, vaccine, or nutrient, into a person's or animal's body. It also refers to the substance itself that is injected. In a broader, non-medical sense, 'injection' can mean the introduction of something new or additional, such as money, energy, or ideas, into a system or situation to improve it.

Examples

Common mistake

A common mistake is confusing 'injection' with 'infusion,' which refers to a slower, continuous delivery of fluid, rather than a single, targeted dose.
